EARTH-SYRINGE.

specification of Lettere Patent.

Application filed September 3, 1907. Serial N o. 391,274. I

To all whom 'it may concern:

Be it known that I, JAMES SAGUIN, a citizen of the United States, residing at Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented a new and useful Earth-Syringe, of which the following is a specification.

My invention relates to earth syringes in which a closed pointed tube supplied with the desired fluid has a means of opening to allow the fiuid to escape.

The objects of my invention are; first, to provide a means for injecting underneath the soil and about the roots of plants or weeds, fluids for various purposes; second, to provide a means whereby a single insertion and withdrawal will automatically inject such material underneath the surface of the ground or into whatever material the same may be inserted; third, to provide a means for limiting the depth of insertion of such device; fourth, to provide a means whereby damaging fluids can be inserted at the roots of obnoxious weeds for the purpose of destroying them without injury to surrounding plants. I attain these objects by the device illustrated. inthe accompanying drawing in which Figure 1 is a cross section of the syringe. Fig. 2 is a side elevation of the same. Fig. 3- is a sectional detail illustrating a modification in the construction of the operating handle or grip. Fig. 4 is a sectional detail of the modified form of the penetrating point of the improved device.

The improved device comprises a tubular member b converging at the lower end to produce a relatively limited discharge aperture and also to produce a point to enable the tubular member to be inserted more readily into the earth. Extending through the tubular member l) is a rod 0J with its lower end pointed and adapted to close the contracted aperture at the point of discharge of the tubular member b and thus serve as a valve element as Will be obvious. Surrounding the tubularmember l) is a tank c and the tubular member has apertures at the lower part of the tank, so that the contents of the tank will flow into the tubular member.

In Figs. 1 and 2 a handle d is attached to the upper end of the tubular member b, while the rod a extends through the handle member and is provided with a plate f upon Patented June 23, 1908.

to the rod c within the handle member is a hand grip p and between the grip and the upper portion of the handle is arranged a spring s, operating between the handle and t e grip p to maintain the rod a yieldably in its downward position, and normally closing c will be retained, and will ow from the implement when the grip p is elevated against the spring s carrying the rod a with it.

With the implement thus described, when it is desired to deposit a liquid around the roots of plants for any purpose it is only necessary to thrust the pointed end 'of the tubular member l) into the soil, .elevate the rod a by pressure applied to the grip p and hold'y the rod elevated until the required quantity of liquid has flowed from the tank, and it is -obvious that the quantity of liquid may be readily gaged by holding the rod a in its elevated position for a greater or lesser length of time. i Surrounding the tubular member Zi be- -tween the tank c and its penetrating oint is a collar g provided with a clamp bollt '11, so that the collar may be adjusted longitudinally of the tubular member, the collar serving as a stop to control the distance in which the tubular member will enter the soil.

The tubular member b may be in two parts as illustrated in Fig. 1, or in one single piece, as illustrated in Fig. 4, but will preferably be in two pieces as illustrated in Fig. 1, to enable the point to be removed when'worn or broken, for obvious reasons. In Fig. 3 is shown a modified construction of the handle member, and the means of connecting the handle to the other parts. In this modified structure the tubular member b extends through the handle and bears against its upper part and is provided with a lateral shoulder between which and the lower portion of the handle the spring s is arranged, the rod a extending above the tubular member and rigidly connected to the handle. By this arrangement, when the implement is to be employed it is thrust into the soil by pressure upon the handle in the same manner as in the structure shown in Figs. 1 and 2, and when the liquid is to be discharged the handle d is simply moved upwardly against the resistance of the spring s, which will operate the its upper end above the handle. Attached i rod a and permit the-discharge of the liquid,

the resistance of the soil being generally.

, sucient to retain the tubularmember'b 1inl position, but if necessary the tubular member may be held in its downward position .byy one hand and actuated by the other hand.

The amount of .liquid that will Ipass' through the syringe into the substance pierced by it, will depend upontheblength of time employed in withdrawing it and can be so regulated. `In this manner the roots of poison ivy,dandelions and other Aplants can besupplied with killingliquids ywithout digging up the ground and without Iinjuring othersurroundingvegetation. Suitable nourishing lluids can `also ybe .applied 'to plants at theproper lace. The force'of gravityis used to prope the liquid into .the substance pierced.

Havingthus described my invention, what I desire to secure by Letters `Patent is I 1. A device ofthe class described comprising a tubular stock converging at one end to `produce a contracted discharge aperture and having oppositely .disposed apertures intermediate its ends, a tank .surrounding the stock and theintermediate aperturesthereof, a handle formed withspaced sides and detachably connected at one side to said stock, a rod extending through the stock and pointed at one end to form a valveforthe contracted discharge apertureosaid stockand extendling at the otherend `through-.the handle, a

stop-,element carried bythe rod and bearing upon thehandle, a grip element carried by said rod Within the handle,a spring embracing the rod betweenthe handle and grip ele- 4rnentto maintain the valve normally closed and permit of an opening of the valve by a lpulling action upon the rod against the tension ofthe spring, and means carried by the stock to control the depth of penetration.

2. -A device of the character described comprising a tubular stock having one end converging into a contracted dischar e aperture and having apertures intermediate its ends, a tank embracing the -stockand its-intermediate apertures, a rod extending through the stock and pointed at one `end to form-'a valve for the contracted discharge aperture,a handle securedto the rod a gripping element,

.and a spring embracing lthe rodV between the handle and gripping element whereby the valve is opened by a pulling action upon'the rod against the action of saidspring 3. A device ofthe class described comprising a tubular stock converging at one end-to in closed position and 4permit of removal of the rodirorn its closed position by a .pulling action upon the same. y
